  • Achilles tendon rupture is a common sports injury encountered in younger populations. Various treatment methods are used for acute and chronic rupture. Several treatments for each condition are available, each having their advantages and disadvantages. In an acute rupture, surgical treatment may be a priority for younger patients or those wishing a quick return to play, but the long-term functional outcome is similar to non-surgical treatment. In addition, the re-rupture rate shows a slight difference between the two treatments. The clinical outcomes are similar regardless of the surgical treatment, but an accelerated rehabilitation program should be accompanied by good results. In chronic and neglected rupture, surgical treatment is preferred over non-surgical treatment. Treatments are chosen based on the size of the tendon defect. This article reviews the current updates in the treatment of Achilles tendon rupture that will help clinicians choose the appropriate treatment.

  • The incidence of Achilles tendon rupture is increasing as more people participate in sports and physical activities. However, whether to treat a complete rupture of the Achilles tendon, conservatively or operatively, is still controversial. Current studies show that the nonoperative treatment of acute Achilles tendon rupture with short-term immobilization for up to two weeks and subsequent accelerated functional rehabilitation with protected weight-bearing results in similar functional outcomes and re-rupture rates compared to those treated surgically. Also, nonoperative treatment does not risk any surgical morbidity such as wound problems, infection, and nerve injury. Therefore, the treatment options for acute Achilles tendon rupture should be carefully chosen in consultation with patients regarding possible clinical outcomes and complications of both treatment options.

  • The changes of forest degradation in North Korea have closely been related to political, economic and social conditions at all different times. The deforestation by local people for their livelihood has been accelerated when the recession has been worsened due to the 1990's collapse of socialism and the years of natural disasters, and the fall of the centralized and planned economy system. The serious recession in the 1990's has brought many changes in the North Korean society since the 2000's. Not only the underground economy, but also the market in which personal trades are occurred have been expanded as the distribution system of the planned economy system had fallen. In addition, even many state institutions have also increased timber harvest for export to acquire insufficient foreign currency. Eventually, North Korea felt the limits of utilization of forest resources under socialism then started to seek measures to restore devastated forest, while realizing the need of support from the international society. Therefore, some NGOs of South Korea started to give financial support on building tree nurseries in which seedlings for planting are produced to help the rehabilitation of the degraded forests in North Korea. Therefore, Planning of the basic directions for forest rehabilitation programs considering to economic and social conditions of North Korea are needed based on the successful rehabilitation experience of South Korea in the 1970's. First of all, relationships which was built after collapse of centrally planned economy between districts, businesses and workers must be consider to rehabilitate forests in North Korea. Secondly, due to the nature of forest rehabilitation projects this is very needs voluntary participation of resident for a long time, and then forest rehabilitation projects can create jobs for local resident, they can obtain continuous income on the forest rehabilitation projects field in order to promote resident's work in forest rehabilitation projects. Thirdly, the rate dependence on forests of the residents living must keep the level down by rural development projects going side by side with forest rehabilitation projects. Fourthly, use of exsisting forest management system in North Korea is also needed to ensure administrative power and labor for grand scale plantations in a short period of time. Meanwhile after the success of Forest Rehabilitation, it is very important to improve exsisting forest management system.

  • This study was performed to investigate the surface properties and in vitro biocompatibility of electrochemically oxidized Ti-6Al-7Nb alloy by anodic spark discharge technique. Discs of Ti-6Al-7Nb alloy of 20 mm in diameter and 2 mm in thickness were polished sequentially from #300 to 1000 SiC paper, ultrasonically washed with acetone and distilled water for 5 min, and dried in an oven at $50^{\circ}C$ for 24 hours. Anodizing was performed using a regulated DC power supply. The applied voltages were given at 240, 280, 320, and 360 V and current density of $30mA/cm^2$. Hydrothermal treatment was conducted by high pressure steam at $300^{\circ}C$ for 2 hours using a autoclave. Samples were soaked in the Hanks' solution with pH 7.4 at $36.5^{\circ}C$ during 30 days. The results obtained were summarized as follows; 1. The oxide films were porous with pore size of $1{\sim}5{\mu}m$. The size of micropores increased with increasing the spark forming voltage. 2. The main crystal structure of the anodic oxide film was anatase type as analyzed with thin-film X-ray diffractometery. 3. Needle-like hydroxyapatite (HA) crystals were observed on anodic oxide films after hydrothermal treatment at $300^{\circ}C$ for 2 hours. The precipitation of HA crystals was accelerated with increasing the spark forming voltage. 4. The precipitation of the fine asperity-like HA crystals were observed after being immersed in Hanks' solution at $37^{\circ}C$. The precipitation of HA crystals was accelerated with increasing the spark forming voltage and the time of immersion in Hanks' solution. 5. The Ca/P ratio of the precipitated HA layer was equivalent to that of HA crystal as increasing the spark forming voltage and the time of immersion in Hanks' solution.

  • As old concrete pavements of over 20years in age are increasing in expressways, the repair and rehabilitation of concrete pavement have become an important issue. Although asphalt overlay is widely used as an alternative to rehabilitate the old concrete pavement, problems due to infiltrated water such as reflection crack and pothole are imposing a very serious threat to its performance. This study proposes waterproof membrane as a solution to minimize the damage due to reflection crack and infiltrated water, and accelerated pavement testing was carried out for the performance comparison of composite pavement with waterproof membrane and ordinary tack coating. The experiment used water spraying to simulate rainfall, and the behavior and moisture resistance characteristics of overlay pavement were analyzed. The experimental result indicated that the strain pattern of waterproof membrane section differed from ordinary tack coating section because waterproof membrane caused the asphalt pavement and concrete pavement to move together. Additionally, since waterproof membrane minimized the infiltration of water and delayed the occurrence of reflection crack by about 70% in comparison to ordinary tack coating method. Moreover, the damage due to infiltrated water also decreased.

  • Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus (T2DM). The our study evaluated the beneficial effect of diet supplementation with Lentinus edodes on hyperglycemia and lipid metabolism in normal and type 2 diabetic rats. The animals were divided into 4 groups: group I(control) rats were fed standard diet (12% of calories as fat); group II (T2DM) rats were fed HFD (40% of calories as fat) for 2 weeks and then injected with STZ (50 mg/kg); group III and group IV rats were continually fed a diet containing 1% and 10% Lentinus edodes for 4 weeks after T2DM induction, respectively. After 4 weeks we determined biochemical parameters such as glucose, insulin concentration, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and glycosylated hemoglobin (HbA1c) concentration were also measured. There was a significant reduction in serum TC and TG in the Lentinus edodes supplement groups. The Lentinus edodes diet supplementation were found to have a potent lipid metabolism improvement as well as LDL concentration decreased and HDL concentration was increased. Concentrations of blood glucose and HbA1c in the experimental groups II were significantly decreased after 4 weeks compared with the control group. The Lentinus edodes diet supplementation is useful in regulating the glucose level, improves the insulin, HbA1c, serum lipid metabolism in experimental diabetic rats. We suggest that Lentinus edodes supplementation may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.

  • Objectives: This study was conducted to evaluate the hair growth-promoting effects by Rumex japonicas Houttuyn ethanol extract (RJHEE) in C57BL/6N mice and HaCaT cells. Methods: The hair growth effect was examined by topical application of RJHEE on the shaved dorsal skin of C57BL/6 mice. Six-week old mice were depilated and separated in 4 groups; CON (vehicle treatment), MXD (2% Minoxidil), and RJHEE (2% and 4%). The treatments were applied daily for 17 days. The hair growth was determined photographically and the hair density, thickness and length were identified by Folliscope. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blotting. In HaCaT cells, the cell proliferation and the protection against H2O2-induced cell damage by RJHEE were analyzed. Results: Our results indicate that RJHEE promote the hair growth, hair density, thickness and length. RHE activate the Wnt/𝛽-catenin signaling and induced the expression of cell survival-related proteins, such as pERK/ERK and Bcl-2/Bax. In HaCaT, RJHEE accelerated the cell proliferation and protected the H2O2-induced cell damage. Conclusions: Our results strongly suggest that RJHEE promotes hair growth by regulating the activation of Wnt/𝛽-catenin signaling and cell survival signaling and protects oxidative stress-induced hair damage. Therefore, RJHEE has a hair growth activity and can be useful for the treatment of alopecia.
